that mesh isn't going to be light proof. when your flowering and when they are in the dark period it needs to be proper dark. for the exhaust fan your better off using an inline fan. you can buy them for around £10 and they will move far more air, and with the 250w lamp you will need it. you can then easily hook up a carbon filter at a later date. these are about £25 and are the best thing for odour control
